The p pe 12 is supported; in engagement with the smoke-stack 15 by means of brackets 19 and these brackets are provided with l laterally extending ears 20' for allowing the brackets 19 to be securely in engagement with the smokestackby means'f'of. bolts 21.

The brackets v19 are provided with centrally located apertures 22 for allowing the vertia cally extending pipe 12 to pass therethrou h.

. .The rearend of the pipe 3 carries a Va ve 23 which is supported by means of the valve stem and'handle'24, and this valve 23 carries a depending pipe .241 which pipe passes a. through a threaded collar 25 for'holding the v pipe in the boiler 1. A strainer casing 26' is suspended from the lower'end of the pipe 24 and comprises a substantially square ody having a collar 27 threaded upon the lower end of the pipe '24 for connecting, the

The strainer body 26' is provided with a plurality of perforations 28 as illustrated in Fig. i ofthe drawing.

It ,should be understoodthat throu h the medium of the valve 23 the supply 0 water to the smoke-stack may be increased or decreased at the will of the operator.

Thespray hood 18 is positioned near the to of the smoke-stack 15 as illustrated in Fig. 1:,ar'1dthis spray hood comprises a substantially conical bodyprovided with a pluralityiof; apertures '29. A pluralityaof partitions 30 are carried within the hood 18 and 1 these partitions are also'provided with apertures 31 for breaking the water up into fine sprays as the water is discharged through the pipe-17. a I

fThe'operation of the'device-is as follows: As the sparks pass from the fire-box the same willpassup through the smoke-stack live sparks which would be discharged from the upper end of the smoke-stack.

It should be understood as stated above that the supply of water may be regulated by means of the valve :23 according tothe amount of cinders and live coals which are being discharged through the smoke-stack Having thus described the invention what is claimed as new, is: y

In a spark arrester of the class described the combination with a boiler, astack, a supply pipe passing through saidboiler, means for controlling the passage through said pipe, a strainer carried by one end of said supply pipe for'preventing the admission of solid substance into said supply pipe, of a cone-shaped spray-hood carried by said supply pipe and positioned in the upper end of said stack, said cone-shaped spray-hood provided with perforated side walls, a plurality of perforated partitions carried wlthin said spray-hood for breaking Water or liquid. passing therethrough into line spray and for discharging a fine spray from the upper end of said stack thereby increasing the draft through said stack.
